Modified polymers


  • Acronym: ECO-BIO-FOAM
  • Project number: 32101
  • Contract period: 1 October 2008 - 30 November 2011
  • Project abstract:
  • Using polymers from renewable resources as an alternative for the conventional ones, contributes, on the one hand, to the saving of non-renewable fuels and on the other hand to the reduction/elimination of post consumer plastic accumulation in the environment. Starch, the main natural polysaccharide, is relatively inexpensive and is used to manufacture biodegradable materials that can be processed into packaging. Because of high hygroscopicity and low physico - mechanical properties, end products derived from starch have improper behaviors in use. Clear advantages presented by this polymer led to finding new solutions for physical and chemical modification of starch with its transformation into new expandable materials for ecological packaging used to transport brittle goods. To create expanded structures, are considered the easiest to apply variants to working conditions. The technology for the realization of new cell type biodegradable packaging is ecological and envisages a controlled process that can translate into production on existing production lines, in economic conditions. The project is based on the following three types of activities specific for 4th program of PNCD2: technological research, experimental development and support activities. These activities are conducted in a consortium of six partners from which five are Romanians and a foreign partner, namely: two research institutes, three universities and a commercial company. Activities considered in the activity plan are tailored to achieve the objective and outcome indicators targeted. Project as a whole, is based on a modern and efficient management concept of balanced correlation of the activities with human, material and financial resources. The project attracts young professionals in research and states the impact of the project. Result indicators are relevant for 4th program of PNCD2.
